What's changed and what's your intention?

See background and explanation in #18039.

TL;DR: due to impl bug in hyper v1, HTTP2 requests with a header size larger than configured max_header_list_size will hang, which can occur in our system because we (and also gRPC protocol) embed error messages in gRPC header. It hasn't been fixed yet, so all we can do is to configure the header list size to a larger value to mitigate such issue.
